Revisit versioning and streamline maintenance adding "bump" and "tag_…

…release" nox sessions (#13)

* feat: simplify versioning by hard-coding value in pyproject.toml

This major version associated with the package is now consistent with the
IDC table version hard-coded in `scripts/sql/idc_index.sql`.

* chore: Add "bump" nox session to streamline IDC index version update

* chore: Add nox session and instructions for tagging a release
